Stop Spd Gain
P1-07= 1
P1-07 Stop Speed Gain Q Q Q Q
The stop speed gain controls the threshold frequency where the positioning algorithm takes control of stopping the drive.
It is based on a minimum threshold of 4.096 Hz with a 1 setting. The minimum threshold is multiplied by this value to
achieve a maximum threshold of 40.96 Hz. This value also controls the rate of deceleration. The positioning algorithm
will bring the drive to a stop in the orient position within 2 revolutions after initiated. The number of revolutions
required to stop may be extended by the marker offset used.
Motor Ratio Num
P1-08= 1
P1-08 Spindle Ratio Numerator Q Q Q Q
The motor ratio numerator is the numerator for the motor ratio equation P1-08: Spindle Ratio Numerator / P1-09:
Spindle Ratio Div. The proper drivetrain ratio between the driven device connect to the position encoder and the motor
must be set for positioning to function properly.
Motor Ratio Div
P1-09= 1
P1-09 Spindle Ratio Divisor Q Q Q Q
The motor ratio divisor is the denominator for the motor ratio equation P1-08: Spindle Ratio Numerator / P1-09:
Spindle Ratio Div. The proper drivetrain ratio between the driven device connect to the position encoder and the motor
must be set for positioning to function properly.
Control Select
Marker Offset
P1-10 Control Select Q Q Q Q
The control select constant sets how the orient control of the drive. The selections are:
0 – Marker Offset – The orient position is maintained as the marker offset or home position.
1 – Sequence Offset – The orient position is incremented to the next sequence step (0 to 15) and new orient position.
2 – Selected Offset – The orient position is selected from the 16 available positions via multifunction inputs.
3 – Serial Offset – The orient position is read from U1-59: Serial Offset.
When using a 1 or 2 selection parameters P2-01 to P3-05 are used to set the orient positions.
